Exercise machine

ABSTRACT

An exercise machine has a small body. The body has a held portion for being held by users. The body is pivotally installed with a rope wheel for being wound by a rope. The rope wheel has a restoring means for restoring the rope to rewind the friction wheel. A friction means is coaxially installed with the rope wheel. A unidirectional bearing is used to connect the friction means and the axis of the wheel. The friction resisting force of the friction means is controlled by an adjust device. Thereby, as the rope is pulled, the friction means will be driven so as that the friction means will generate resisting force. Since the body is small, and the friction force between the friction wheel and the friction strip is not too large, the exercise machine is suitable for the rehabilitated patient and for general users engaged in gymnastic exercise.

FIELD OF THE INVENTION

[0001] The present invention relates to exercise machines, andparticularly to an exercise machine with a small volume. The exercisemachine can be used in the human by a tying strip. Since the body of theexercise machine is small, and the friction force is not too large, theexercise machine is suitable for the rehabilitated patient and forgeneral users engaged in gymnastic exercise.

BACKGROUND OF THE INVENTION

[0002] The prior pulling-rope exercise machine has one rope. One end ofthe rope is suspended with a weight so that the user may pull theweightt by applying a force. However, these prior art exercise machineshave large volumes and is difficult to be transferred. Furthermore, apulling-rope exercise machine has an elastic rope. A user may pull anend portion of the rope to extend the length of the rope, but the ropeis restored by the restoring force of the rope itself.

[0003] Any kind of polling-rope exercise machine must need a furtherforce to restore an extending rope so that the pulled burden and theprolonged rope may restore slowly, otherwise the weight will generatenoises and possibly hurt the user or other people aside the exercisemachine if the rope is restored quickly.

[0004] As a result, in designing an exercise machine, the largerestoring force, elastic force and gravitational force must take intoconsideration. However, this will induce the complication in design.

SUMMARY OF THE INVENTION

[0005] Accordingly, the primary object of the present invention is toprovide an exercise machine, wherein the tying strip passes through anear of the body. Each of two ends of the tying strip has a respectivesticky strip. As the tying strip is used to tie the user's body, thetying strip can be fixed by the two ends of the sticky strip. Since thebody is small, and the friction force between the friction wheel and thefriction strip is not too large, the exercise machine is suitable forthe rehabilitated patient and for general users engaged in gymnasticexercise.

[0006] Another object of the present invention is to provide an exercisemachine, wherein one side of the body has a handle for being held by theuser and the tying strip is installed with at least one buckling ring.The fixing means of the body is directly connected to the buckling ring,and thus the user may hold a held portion of the body so as to pull therope for exercise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] In order that those skilled in the art can further understand thepresent invention, a description will be described in the following indetails. However, these descriptions and the appended drawings are onlyused to cause those skilled in the art to understand the objects,features, and characteristics of the present invention, but not to beused to confine the scope and spirit of the present invention defined inthe appended claims.

[0021] Referring to FIGS. 1 to 4, the exercise machine of the presentinvention is illustrated. The exercise machine includes a body 10, atying strip 17, and a handle 61.

[0022] The body 10 has a small volume and one side thereof is formedwith a held portion 101 for being held by the user's hand. One surfaceof the body 10 has a concave cambered back 102. A receiving space 103 isformed in the body 10. In this embodiment, the body 10 is formed by twocasings 11. After the two casing 11 is assembled. A hole 104 and a longgroove 105 are formed at a top thereof. The hole 104 serves for beinginstalled with a cover 13 having a via hole 131. A periphery of thecover 13 has an annular trench 132. The inner edge of the via hole 131of the cover 13 has a round flange 133. Each of the interior of the twocasings 11 has a respective positioning block 111 made of metal powders.Each of the positioning block 111 has a hole 112. A shaft 14 passesthrough the two holes 112. The upper side of the hole 112 of thepositioning block 111 has an axial pinhole 113 for being inserted by apositioning pin 15. Two sides of the interior of the two casings 11 haverespective sliding grooves 106. Each sliding groove 106 receives aninserting piece 16. An outer side of the inserting piece 106 has an ear161.

[0023] The tying strip 17 may pass through an ear 161 of the body 1.Each of two ends of the tying strip 17 has a respective sticky strip171. As the tying strip 17 is used to tie the user's body, the tyingstrip 17 can be fixed by the two ends of the sticky strip 171.

[0024] A wheel 20 is installed to the shaft 14. A rope 21 winds throughthe wheel 20. One end of the rope 21 protrudes out of the via hole 131of the cover 13 for being combined with a fixing means 60. The fixingmeans 60 is connected to a fixing ring 611 of the handle 61. At one sideof the center of the wheel 20 has a radial slot 201. A pin 141 passesthrough the shaft 14 along a radial direction. The pin 141 is receivedin the slot 201. One side of the wheel 20 is a restoring means forpulling the wheel 20. The restoring means is positioned between thewheel 20 and the plate 22. The plate 22 has an approximate round shape.In this embodiment, the restoring means is a spiral spring 23. Thespiral spring 23 has an outer end 231 and an inner end 232. The outerend 231 of the spiral spring 23 is directly hooked to the wheel 20. Theinner end 232 is hooked to the positioning pin 15 of the body 1 0.

[0025] At one side of the wheel 20 corresponding to the spiral spring 23is installed with a unidirectional bearing 24. The unidirectionalbearing 24 is installed with a friction means. In this embodiment, thefriction means is a friction wheel 30. An outer periphery of thefriction wheel 30 is enclosed by a friction strip 31. The contactbetween friction strip 31 and the friction wheel 30 is controlled by anadjust device 40. In this embodiment, the adjust device 40 is fixed tothe body 10 by a fixing frame 41. The fixing frame 41 is an approximateU shape plate. The fixing frame 41 has a penetrated though hole 411. Anapproximate rectangular adjust block 42 is installed in the fixing frame41. The adjust block 42 has a threaded hole 421. The though hole 411 ofthe fixing frame 41 is passed through by a stud 43. The stud 43 isreceived in the long groove 105 of the body 10. One end of the stud 43is installed with a button 431. Another end of the stud 43 has athreaded section 432. The threaded section 432 is screwed to a screwhole 421 of the fixing frame 41. One end of the friction strip 31 isfirmly secured to the adjust block 42. By rotating the button 431 torotate the stud 43, the adjust block 42 may move upwards or downwards inthe fixing frame 41. The adjust block 42 resists against the U shapefixing frame 41 so as not to rotate. Therefore, the friction forcebetween the friction strip 31 and the friction wheel 30 is adjusted.

[0026] A guide means is installed in the body 10. In this embodiment,the guide means is two guide wheels 50 which are pivotally installed tothe body 10 below the cover 13. One end of the rope 21 wound around thewheel 20 passes through the two guide wheels 50 and then the rope 21protrudes out of the via hole 131 of the cover 13. Thereby, when therope 21 is pulled or wound, by the guiding of the two guide wheels 50,the resisting force on the rope 21 is reduced.

[0027] Referring to FIGS. 5 and 6, conditions for using two exercisemachines at the same time are illustrated. In using, two exercisemachines pass through a tying strip 17 and then the tying strip 17 windsaround the waist of a user. Then the back 102 of the body 10 resistsagainst the waist of the user. By the sticky strips 171 at two ends ofthe tying strip 17, the tying strip 17 is positioned. The user holds theheld portions 101 of the ropes 21. When the user applies forces to theropes 21 to drive the wheels 20 to rotate, the spiral spring 23 will bewound tightly. The wheel 20 will rotate around the shaft 14 and thus theunidirectional bearing rotates so as to drive the friction wheel 30 torotate. Since the wheel surface of the friction wheel 30 is in contactwith the friction strip 31, when user pulls the rope 21, a force isnecessary to resist against the friction force between the frictionwheel 30 and the friction strip 31. Thereby, the effect of exercising isachieved. Since the body 10 of the present invention is small, and thefriction force between the friction wheel 30 and the friction strip 31is not too large, the present invention is suitable for therehabilitated patient. Furthermore, the present invention is suitablefor general users engaged in gymnastic exercise.

[0028] When the user does not apply force, the restoring force of thespiral spring 23 will drive the rope 21 on the wheel 20 to rewind. Inthe traveling path of the rope 21, since the unidirectional bearing 24only rotates unidirectionally, the friction wheel 30 will be driven. Thespiral spring 23 only has the function of pulling the rope 21 and thusone with a small twisting force is suitable, which will not cause aburden to the user. When the rope 21 is restored, the user only needs toapply a slight force for resisting against the restoring force of thespiral spring 23. Therefore, no exercise hurt will occur when the rope21 is pulled back as that induced in the prior art design.

[0029] Moreover, the user may adjust the contact between the frictionstrip 31 and the friction wheel 30 by the adjust device 40 so as tochange the friction force between the friction wheel 30 and the frictionstrip 31. As illustrated in FIG. 7, in using, the user only needs torotate the button 431 so that the threaded section 432 of the stud 43drives the adjust block 42. The adjust block 42 is fixed to the fixingframe 41 to move upwards and downwards so that the adjust block 42 willdrive the friction strip 31. Thereby, the tightness of the frictionstrip 31 contacting the friction wheel 30 is adjusted. The tighter thefriction strip 31, the larger the resisting force from the frictionbetween the friction strip 31 and the friction wheel 30. Thereby, theuser has a larger exercise effect. If it is desired to reduce thefriction resisting force, the above said method is performed along areverse direction.

[0030] In the process of pulling the rope 21, since the rope 21 passesthrough the two guide wheel 50 and then protrudes out of the body 10from the cover 13, and a flange 133 is formed in the via hole 131 of thecover 13, when the rope 21 passes through the cover 13, the rope 21 willnot be pulled so as not to be trimmed in the via hole. The gap betweentwo guide wheels 50 only allows the rope 21 to pass through. Therefore,the rope 21 is guided by the two guide wheels so as to reduce theresisting force as the rope 21 moves forwards.

[0031] Other than above said exercise way, further referring to Fig. atleast one buckling ring 71 is installed in a tying strip 70. A fixingmeans 50 of the body 10 is directly connected to the buckling ring 71.The user may hold a held portion 101 of the body 10 so as to move thebody 10. Then, the rope 21 moves. Besides, the referring to FIGS. 9 and10, other than being tied to the waist of a user, the tying strip 70 maytie the thighs or shanks of the user. Referring to FIG. 11, in thisembodiment, the body 10 is engaged with the tying strip 17 and then thetying strip 17 is used to tie on shank of the user, while another shankof the user is tied by a tying strip 70 with a buckling ring 71. Thefixing means 60 of the body 10 is connected to the buckling ring 71. Theuser may pull the rope 21 by expanding the legs. With reference to FIG.12, the user holds the held portion 101 of the body 10 by one hand andholds the handle by another hand so that the pull the rope 21 forexercise.

[0032] In summary, in the present invention, a pullable rope isinstalled in the body. The rope has a proper resisting force. By thetying strip to pass through the ears at two sides of the body and stickystrips at two ends of the tying strip serves to fix the tying strip at aproper portion of the user. Since the volume of the body is small. Otherthan general exercise, the present invention is also suitable forrehabilitated patients. Moreover, since one side of the body has a heldportion to be held by the user directly and the tying strip is installedwith at least one buckling ring, by the fixing means of the body isdirectly connected to the buckling ring of the tying strip, the user mayhold the held portion of the body to move the body and then pull therope.
